Can I vibecode Fathom Analytics?
// one session, and a personal version you can actually use
A simple privacy analytics clone is very buildable; the paid service is hosted compliance posture, uptime, data retention, and polished reporting.

The moat outweighs the price: rebuilding this is a project, not an evening.
Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.
What you build
Collect pageviews/events via JS, aggregate metrics, show simple dashboards, and send reports.
what you need
- hosted backend
- tracker script
- database
- domain/SSL
- backups
- bot filtering
Useful because several analytics apps are genuinely cloneable now.
The prompt
One session with a coding agent and your version runs.
Build me a privacy-first web analytics service to replace Fathom Analytics. Requirements:
- Node + Express + better-sqlite3, one small app I deploy on my VPS behind
Caddy or nginx.
- The tracker: a single script tag under 2 KB that sends pageview beacons
(path, referrer, screen width) with navigator.sendBeacon. No cookies.
- Count unique visitors without storing personal data: hash IP + user agent
with a salt that rotates daily, then drop the raw values.
- Filter obvious bots against a user-agent blocklist before counting.
- Dashboard page: pageviews, uniques, top pages, top referrers over 7/30/365
days, one Chart.js line chart plus tables. Protected by a single bearer
token from .env, no user accounts.
- Retention: raw events kept 30 days, daily rollups kept forever, pruned by a
nightly node-cron job.
- No cookies, no personal data at rest, no telemetry of its own.
- Out of scope: email reports, team seats, billing. One site, or a short site
list in config.
- README: deploy steps, adding the script tag, and a plain note that this is
polite analytics, not a legal compliance product.Prompt generated from the data on this page, not reviewed by hand yet. In English on purpose — it is the language coding agents work best in.
What you lose
- managed infrastructure
- privacy/compliance messaging
- email reports
- uptime
- support
- billing
Why people still pay
They pay to avoid maintaining analytics infrastructure and privacy copy themselves.
moat: Infrastructure scale Brand and trust what a moat is
hosting/compliance positioning
